Gnamptogenys sulcata (Smith 1858)

This species inhabits lowland rainforest, and is known from isolated workers, usually encountered in fresh treefalls or Malaise traps. Relative to the morphologically similar G. tornata, it appears to be more arboreal. In contrast to G. tornata, G. sulcata is rarely collected in Winkler samples.

Mexico to tropical South America (Lattke 1995). Costa Rica: La Selva and Osa Peninsula.

Promesonotal suture absent; scapes surpass margin of vertex when laid back; mandibles smoothly curving such that basal and apical margins form a continuous convexity; head in back of antennal insertions black or nearly so; mandibles straw yellow, contrasting sharply with black of cranium; mesosoma, node and gaster varying from black to yellowish-red; eyes relatively large and elongate (eye length = 0.36, width = 0.23, n=2 workers).
